BEVERAGE-CARBONATOR.

Application {iled April 29, 1903.

' One Hundred and Twenty-third street, New

York, county of New York, State of New York, have invented certain new and usey ful Improvements in Beverage-Oarbonators,

fully described and represented in the following specificaticn and the accompanying drawings, forming a part. of the same.

, The present invention relates to improvements in the apparatus shown in my Patent No. 702,718, granted June 17 1902, for oarbonator for beverages.

One object of the present improvements is to permitthe construction'of the disks or pans with very thin wire-cloth or fibrous woven cloth instead of metal when desired, which is edected by stretching the ed e of the cloth over a supporting-hoop' and locking it thereon by an outer clampin -hoop.

Other improvements relate to t e stop which holds the disks in place, to the bolting devices for the casing, and to the distributerinlet for the gas. l*

Figure 1 is an elevation of the apparatus, shown in section a little at yone side of the center line, the parts being in sectionwhere hatched. Figs. 1a and 1b show alternative forms for the float-lever x. Fig-"2 is a horiv zontal section of the parts which are intersected by the plane 2 2 in Fig. 1. Fig. 3 isa plan of part f the carbonator-shell and of the bolting-ring upon the same.. Fig. 4 is an elevation or edge view of part of the boltingring, and Fig. 5 isa section of the same on line 5 5 in Fig. 4. Fig. 6 is an ed e view, and Fi .f 7 a side view, of one of the olts for ,the bo ting-ring, and Fig. 8 shows one edgefof the base with the notches for the bolts. Fig.. 9 is a detached view ofthe combined tie-rod and stop. Fig. 10 is an alternative ccnstrucy tion forthe same.

a designates'the shell or casing of-thecarbonator, which constitutes", the gas and water chamber and which is shown cc nnected with the bottom b by means of a bolting-ring c, secured at the bottom of the shell, and T-headed bolts d, inserted through the ring and the bottom. The bottom is formed with radial notches b (see Fig. 9) to insert the bolts laterally, with the nuts already appliedto their lower ends, and the bolting-ring is provided with'radial bolt-holes d2, shown with their Specification of Letters Patent.

outer ends closed, through which slots the T-heads d of the bolts may be passed fromthe lower side. The bolting-ring is forme with a flange D, which is attached to the lower end of the carbonator-shell (L and forms a seat for contact with a packing 7) lupon the bottom b. A groove D is formed in the surlface of the bolting-ring adjacent to the flange D to receive the heads d of the bolts and is adapted to fit such bolt-heads and hold them from turning, as indicated by the bolt-head d in Fig. 3. The bolt-holes d2 are closed at their outer ends for the purpose of strengthening the bolting-ring. The bolt-heads d are shown in Figs. 6 and 7 tapered upwardly, and the bolt-holes d2 are shown in` Fig. 4 tapered outwardly at their lower e/nds to facilitate the insertion of the bolt -heads upwardly through the slots, which are closed at their outer ends.

In Fig. 1, where ten disks are shown within the casing, -the lower two disks are shown bracedwith studs r; but the upper seven disks are represented without any such suports. An outlet-nozzle gis extended through the bottom b, and a gas-inlet nozzle f is carried inward through the bottom, and a distributer is secured u on the same, such distributor consisting of t e hollow shank F, screwed upon thenozzle and extendedf'upward through one or two of the disks and having arms F extended` in diierent directions between the disks and provided upon their under sides with holes to distribute the gas at many points. The hollow shank F is made detachable from the nozzle to permit the application of the distributor above the lower disks. moval of the disks from the carbonator for "cleaning is greatly Jfacilitated by securing the greater partfof the disks together in a loose or movable; nroup by means of a tie-rod en tended through the cenfter. The gas introduced at the inlet is prevented from escaping directly'. to the outletby locating the'distwo of the lower disks, which' retard any downward flow of the gas. Such arrangement is best effected by making the lower disks separate from the gro-up having the tie-rod. Such loose disks may be set upon vthe bottom before the distributer is connected with the inlet, and such connection is then effected by screwing the shank F upon the nozzle, holes or apertures being made through the loose disks where such XOO connection is effected. rlhe connected disks are then set upon the top of such loose disks. The distributer-arms are shown in Fig. 3 in the form of a cross g but the form is immaterial, provided the distributer is appliedx above one or two loose disks and the shank of the distributer connected with the nozzle through such disks. A water-outlet nozzle g is inserted through the bottom b at the side opposite the inlet-nozzlef. fi water-inlet nozzle 7L is inserted through the shell near the top and rovided with a valve-seat i, which is closed y a valve y, actuated by a lever and float :1; to maintain the desired water-level w in the apparatus. All the disks except those below the distributenarms F are shown-connected by a tie-bolt Q and a stop inserted between the top of such tie-bolt and the top of the carbonator to hold the group ofdisks from rising'within the shell. The lever of the float is Shown extended across the carbonator with the float upon the same diametri'cal line as the Valve'fi, and as the lever would necessarily cross the center of the shell it would intersect a central stop, if one be used, as hereinafter described. To terference with the stop, the lever of the float is formed tol clear the stop, which may be done by reflexing the lever, as shown in Fig.

la, or by slotting the lever, as shown in Fig.

1b. The bottom b is dished, and a perforated grating k is inserted within the casing, resting upon the bottom and forming a chamber Z in the bottom, which chamber connects with the outlet-nozzle g. The nozzle g is provided with a pipe g to draw carbonated wa- 'ter from the nozzle, such water passing through the grating to reach the nozzle.

A. safety-valve (designated K in Fig. 1) is shown upon the center of the shell at the top to relieve the pressure at a certain predetermined limit and has a hand-lever 19 to vent the gas or air when required.

The disks n are shown made of woven fabric, like cheese-cloth or muslin, which are held in form by distending the fabric over a wooden or metal hoop u, as shown in Figs. 1

'and 2, and gathering the edges of the fabric firmly against the outside of such hoop and pressing another hoop u downward outside of the same, so that the edge of the flexible fabric is clamped between the hoops, and thus held securely. The hoops keep the fabric distended and greatly stifl'en the edges of the disks and adapt them to be handled without injury to the disks in assembling the parts to ether to form the carbonator. The group of disks above the distributer-arms F is shown connected together detachably by a tie-bolt g, with acollarq at the upper end and a nut r2 at the lower end of the group. Bushings or sleeves s are shown upon the bolt between the disks to space the disks apart at the center and sustain the clamping pressure of the nut. The loose disks below the dissiagne tributer are shown spaced apart and supported intermediate to the eenter and rim by studs or blocks 7', as shown in Fig. 1` The studs'are not shown upon the disk in Fig. 2, as the view shows the under side of the disks above the level of the distributer with the nut r2 at the lower end of the bolt g. All the in.

ternal parts of the apparatus excepting the disks when made of woven fibers are coated with block-tin to prevent corrosion by the acid-water. v

v1Nhen the gas is first admitted to the carbonator and only atmospheric pressure exists in the upper part,l thc air is vented by the valve K, and the g-as under pressure rises rapidly through the perforations of the disks and tends to lift the same. The saine thing occurs when a large amount of carbonated water is drawn from the shell, thus causing the gas to enter rapidly.

Heretofore a stop has been supported upon the shell of the carbonater to contact with the edges of the disks, asshown in my Patent No. 702,718; but such'a stop cannot be attached directly to the sides of the shell, as it would injure the block-tin lining, and it is therefore necessary to extend it upward with in the shell to the safety-valve, to be secured thereby. Such a stop involves a good deal of bending and fitting of the flat metal of which it is formed, and to avoid such bending and fitting I have deviseda stop fitted directly between the tie-rod and the top of the carbonator, the stop thus operating upon the disks at their central point instead of at their edges. Such central stop (lettered t) is shown integral with the tie-rod in Figs. l and 9, and

its upper end is arranged to contact with the fitting which secures the safety-valve K upon the shell. The shank of the safety-valve is necessarily extended through the shell and is held therein by a nut or collar 11, as shown in F ig'. 1,. through which a lpassage extends to discharge the gas to the safety-valve. By Contact with such collar the top of the stop is prevented from bruising` the shell or fromI bending the same when the carbonator is in transportation jarred or turned in such manner as to throw the weight of the disks against the stop. Instead of attaching the stop to the tie-bolt of the disks it may be formed, as shown in Fig, 10, with a threaded socket t4 at the top adapted to screw upon the collar 11 of the safety-valve, holes t5 being formed in the bottom of the socket, as shown in F igjlO, to permit the escape of gas to the safety'- valve. It is immaterial whether it is the safety-valve or some other fixture upon the center of the shell which supports the thrust of the stop, as any such fixture would serve to stien the shell in' the desired manner IOO IIO

IZO

where the upward thrust of the stop is sustained.

Patches of cross-lines are shown in Fig. 2 to ndicatethe woven character of the disks,

which may be made of-very thin wire-cloth l nozzle F, the gas being supplied at a suitable pressure, as one hundred and sixty pounds, to permit the charging of siphons with the carbonated water. The gas is discharged downwardly by the distributer, and is thus diffused beneath the disks and rises through the numerous pertorations of the disks, and is thus not only caused to rise more slowly, but to be more evenly distributed in the receptacle when rising. Such distribution of the gas through the numerous perforations cause it to be absorbed by the water with great rapidity. The stop applied to the disks prevents the gas from lifting the disks when entering rapidly,the air in the upper part of the carbonator being discharged by `opening the relief-valve, and the carbonator is thus filled with gas and carbonated water 1n. readiness for use.

1 wardly through the perforations in the disks,

as incertain classes of carbonators; but the pertorations'are used to distribute the gas evenly throughout the receptacle as it rises through the water, and thus promote its absorption with the greatest rapidity.

I have found that the improvements described herein are of great practical value in constructing and o erating the carbonator, as the bolting-ring (siown herein at the lower end of the shell) avoids the careful fitting of hook-bolts to a thin locking-ring upon the shell, as shown at b c in myPatent No. 702,718, and substitutes therefor thefclosed bolt-holes d2, which may be readily cast in the boltingring, and the bolts with T-heads d, which are readilytormed b'y drop-forging and do not require to be carefully finished to hold securely. W ith the construction shown in my atomsaid patent it was common for the joint ot the shell and base to leak, as the hooked heads of the bolts were easily strained by the high pressure employed in the shell, while the bolts d in my present construction are not liable to yield, as their heads are supported at oppo site sides.

The bolting-ring is preferably made so that the heads of the bolts d lie below the top of `the iian'ge D, which is indicated by the relation of the groove D" to the top of such flange in Fig. 5, as the bolts thus pull the shell downwardly through theagency of the upper riv- (Shown in Fig. 5.) 'The central stop avoids the necessity of fastening anything to the shell of the carbonator, as inmy former construction, while the employment of one or two loose disks below the movable group permits the location of the distributer above such disks, and thus erlectually prevents the gas as-it enters the shell from being carried to the outlet g. When the gas is permitted to reach the outlet, it is mixed with the Water without absorption and produces a great deal of sputtering when the carbonated water is drawn. By locating the distributer above certain of the disks such sputtering is wholly prevented.

Having thus set forth-the nature ot the invention, what is claimed herein is- 1. In a carbonator, the combination, with a shell having means therein Jfor mingling the gas and water, a water-inlet, a gas-inlet, a water-outlet, and a removable bottom, of' the flange D attached to tlieshell and having below its upper edge the bolting-r'ing with annular groove D to sustain bolt-headsbelow the top of the llange D, .the oblong radial boltholes d2 in the bo'ltmg-ring, the integral ring c closing the outer ends of the slots, and the base l) having slots 7) corresponding with the bolt-holes, with bolts d having nuts thereon and T-heads d adapted to pass upwardly through the bolt-holes d2 and turn into the groove D, substantially as herein set forth.
